Dear Master,
I have a problem regarding coating application on our inner tank surface with SWRO (Sea Water) service.
We have done surface preparation at first. Then, we found any scattered pitting in some location with dept more than 1 mm.
Do you have any advice regarding this particular...
Hmmm. Okaaay noted LittleInch.
I hope following the best practice is okay as long as there's no probs for our piping system.
Thank you very much for your kindly advice guys.
Yes @MJCronin, I also think that there is recommended practice regarding this pressure increasing rate.
I have reviewed ASME also. But From ASME, its just noted that "The pressure shall be applied by raising gradually to hydrotest pressure specified". They are not mentioned about how much...
Dear @LittleInch,
Thank you for your opinion.
So that condition will be vulnerable to the pipe?
Do you think that this phenomenon is just happened like water hammer?
And, could you tell me, is there any standard or code that regulate how much pressure increment rate allowed?
Thank you very...
Dear all,
Just want to discuss. Is there any effect of sudden pressure on Piping system?
We did hydrotest for piping yesterday. Based on procedure, hydrotest shall be done in several stages. 25%, 50%, 75%, finally 100% MAWP. But unfortunately, we had problem with the system and it was difficult...
